Specification of Letters Patent. Patollted Aug. 22, 1922.

Application filed September 28, 1916. Serial No. 122,631.

' To cilia/10m. it may concern:

include in their organization fastener inserting mechanism. The invention is herein shown. by way of illustration, as embodied in a pulling-over machine for use in shoe manufacture and having features of novelty which are the sole invention of Fred Ricks, one of the present applicants, and are claimed in Patent No. 1,346,256 granted on July 13, 1920. but it will be apparent from the following description that the invention, in its broader aspects, is not restricted in its applicability to machines involving such novel features nor, in fact, to machines for use in pulling uppers over lasts, but is of general applicability to machines employed for various purposes.

Features of the invention are to be recognized in a novel construction and arrange ment of means for effecting the delivery or presentation of fasteners to fastening mechani m. One important object of the invention is to provide effective means for delivering fasteners under certain conditions where the force of gravity may not be relied upon .as heretofore to effect invariably the transfer of fasteners from the source of supply and their proper presentation to the fastening means, for example where the fasteners are to. be inverted and driven upwardly into the work. The construction shown comprises. means for separating fasteners point downward mthe manner'cus tornary heretofore, with pneumatic means for inverting the' fastencrsand for deliverv section, of a portion of the mechanism. shown ing them point upward to devices whereby they are supported for the driving operation.

ore particularly, the construction shown comprises conduits, the receiving ends of which are over the fasteners as the latter are supported in separated position, with means for delivering a blast of air to lift the fasteners and force them head foremost into the conduits, the latter being curved to 55 effect an inversion of the fasteners and to deliver them point upward. In the illustrated application of the invention to a machine in which upper securing fasteners are driven upwardly at the toe end and the opposite 0 sides of the forepart of a shoe supported bottom downward, a plurality of fasteners are inverted and delivered by the pneumatic 'means substantially simultaneously to the different fastening mechanisms.

The invention also provides novel means for transferring each fastener from a point of presentation or delivery, to which it may be advanced pneumatically, as hereinbefore explained, or otherwise, into such relation to the respective driving member as to permit it to be driven, and such means constitutes a further feature of the invention. In the construction shown the fasteners, after having been inverted and advanced pneumatically to their respective pointsof presentation, are received in carrier plates which are moved relatively to the driver bar arms on which they are mounted'to present the fasteners to the drivers. 8.0

The above and other features of the invention, including certain details of con struction and combinations of parts, will now be described with reference to the accompanying drawings and pointed"out in 5 the claims. I

The machine herein shown includes in its eneral organization many features of a well own type of pullin -over machine such as exemplified in rior lnited States Letters Patent No. 663.77 ranted u on an application of R. F. Mci eely on ccember 11, 1900, and exemplified also in various modi= fications in other United States Letters Patents of which it is only necessary herein to refer to Patent No. 1,029,387, granted on an application of R. F. McFeely on June 11, 1912. In order that the invention may be more clearly understood, the general features of construction of the illustrative machine, some of which are set forth in detail in Patent No. 1,346,256 above mentioned, will be briefly described, and where convenient the reference characters of the prior Patent No. 663,777, and in certain instances also of Patent No. 1,029,387, will be used to indicate corresponding parts.

The operative parts of the machine are supported upon a frame comprising front and rear plates 2 and 4 respectively, connected by stay rods 6. Bolted to the front frame plate 2 and suitably supported at the top of the rear plate 4 is the head portion 8 of the machine upon which are mounted the various instrumentalities for operating upon the shoe, and operating means for such instrumentalities comprising the cam shaft D which in the present construction is supported vertically with its driving pulley 986 in a horizontal position between the frame plates. The operation of the machine is controlled by a treadle X. connected to one end of a lever X, to the other end of which is pivoted a short rod X which serves in the usual way, upon the operation of the treadle, to actuate automatic means for retracting a brake shoe 982 from the pulley 986, such means acting through a rodX and a lever X to operate a rod 984 whereby the clutch (not shown) is actuated to cause the pulley 986 to be driven by means of a suitable belt 65 to efiect the first portion of the cycle of masses 0 erations of the machine, after which the c utch is automatically disconnected and the brake ap lied through the connections above describe by such means as are fully disclosed in prior Patent No. 663,777.

When the work is in position in the machine the last, with the upper positioned loosely upon it, is supported, as indicated by dotted lines in Figs. 1, with the rear portion of the upper on the last in engagement with a heel rest 10 and with the forepart of the sole or insole on the last positioned upon a sole rest 12. In this position the upper is engaged by the usual toe and side grippers, ofwhich the toe ri per is seen at 14 in Fig. 1 and is pu le over the last auto matically during the first portion of the cycle of operations the machine then coming automatically to a stop. The toe gripper is connected to an updraw lever e which is pivoted on a rod 152 and has connection at its rear end through a rod 170 and a spring 176 with a cam slide 172 operated by a cam on the cam shaft D. Through movement of the slide 172 the toe gripper is thus operated to pull the upper yieldingly with a force determined by the de ree of compression of the spring 176. The side grippers are similarly operated by levers 15 1 pivoted on the rod 152 and connected through s rings 146 and rods 136 to a cam slide 134.

uring the second half of the cycle of operations, which takes place upon a second de- 7 pression of the treadle X, the margin of the upfper is carried inwardly under the bottom 0 the last and, following movement of fastener driving means comprisin driver bar arms 672, 674 and 676 inwardly under the last bottom, the fasteners are inserted to retain the upper in its pulled-over position. 1 While the machine is at rest between the two periods of the cycle of operations, the operator is afforded opportuntiy to efi'ect such adjustment of the upper on the last as may be necessary in order to correct any inac- 110 curacy in its position, through the manipulation of various instrumentalities of which it is only necessary herein to refer to handles 158, each of which has operative connection with one ofthe side gripping instrumen- 115 talities, and a handle e connected with the toe gripper operating lever 6, whereby the operator is enabled to manipulate the different grippers as desired. Pivoted on the handle 6 is a lever 226 connected by a 1 7 link 226 to the usual lever 226, whereby the opening of the toe gripper may be effected.

The work positioning means and the 0pcrating instrumentalities hereinbefore described are ,so arranged that the heel end of 5 the last is supported substantially over the front frame plate 2 of the machine and the last is inclined upwardly from its heel end toward the rear of the machine at such an angle that the operator, as he maintains lee 1,4ae,sse

- operator that he may manipulate them without the necessity of changingmaterially his viewpoint with reference to the work and without-in any Way obstructing hisview of the work. In order to insure these results the handles referred to are preferably extended, as shown, to positions somewhat higher than the work and far enough forwardly to permit the operator to manipulate them without stooping. In the construction shown the last is positioned at an incline of substantially 50 degrees to the horizontal, this angle having been determined as particularly satisfactory for the objects in view under average working conditions,

but it should be understood that the invention is not limited to a construction in which the last is inclined at the precise angle shown. It will be observed by reference to Fig. 1 that the operative portions of the machine are substantially atthe rear of a vertical projection of the treadleX, and by reason of this arrangement the operator may maintain a single position close to the work both for operating the treadle and for manipulating the upper on the last.

The construction shown is particularly adapted for driving fasteners in the form of tacks, as is usual in machines of this type, but the invention in many of its aspects is not limited to the use of tacks. For assorting and arranging the tacks the machine shown includes a tack pot 400 of any usual form and raceways 16. equal in number to the number of tacks to be driven at each operation, upon which the tacks hang suspended in rows by their heads. The tack pot 400, in the construction shown, is supported upon a bracket 18 and is rotated from the cam shaft D through connections including a bell crank 20 and a link 22.

Mounted to reciprocate in the usual manner at the lower ends of the raceways are separator plates 24 (Fig. 7) which are so formed (Fig. 5) that when the tack, shown at a has been advanced to the inner end of .the groove 26, it is still suspended by its head and is not permitted to drop through the usual opening 562 in separator plate 558 (Fig. 6 as heretofore constructed. The tack, as thus supported, is moved into alignment with an opening 28 in the brac e platewhich serves to support the raceways. Communicating with this opening at its lower end is a pipe 32 which leads to a valve 34 arranged to control the admission to the pipe 32 of compressed air'from a supply pipe 36 which may communicate with an air pump or with any-suitable supply of air under pressure. The coristructzon shown comprises a single'pipe'32 leading to :the several openings 28, but it will be under stood that several conduits 32 may be arranged to communicate with the several openings if desired. Positioned over the separators 24 is a bar 38 p Homded with openr ings 40 which are over te heads of the respective tacks after the latter have been moved by the members 24 to separated position. Associated with each of the openings 40 is a block 42 pivoted to the bar 38 and having an opening 44 arran ed to aline with the opening 40 when the b ock 42 is in the position shown in Fig. 7 and in full lines in Fig. 8. Raceway covers 46 rest upon the blocks 42, and upon the lifting of any one of these covers the corresponding block may be swung aside, as indicated by dotted lines in Fig. 8, in order to permit the raceway to be cleared in case a tack becomes wedged therein.

Supported at one end in the bar 38 and communicating with the respective openings 40 are curved conduits 48 which lead to various points of delivery or presentation for the tacks to permit them to be supplied to the difierent tack drivin instrumentaliti es. The conduits 48 are, it will be understood, equal in number to the number of tacks to be driven at each operation and are grouped and arranged as required with reference to the articular points at which the tacks are to e driven in the work, the delivery ends of these conduits being sup.- ported on brackets 50 on the machine frame. With this construction and arrangement, a blast of compressed air from the pipe 32 will lift the tacks from the separator plates 24 and force them head foremost intoand through the respective conduits 48 to their. points of delivery, the curved form of the conduits 48 causing the tacks in their pas sage to become inverted in such manner as to be finally presented point upward.

The driver bar arms 672, 674 and 676 have their usual movement toward and from driving positions with respect to the margin of the last bottom. With reference to Figs. 9 and 10, the driver bar arm 676, which is one of the side arms having means for drivingtwo tacks simultaneously in the side margin of the last bottom, is arranged for as i corresponding conduits 48 are positioned; adjacent to and at one side of the path of movement of the driver bar arm, and the machine is provided with means controlled by the movement of the arm for effecting a transfer of the tacks from delivery positioninto position to be driven. The construction shown for edecting this transfer com rises a carrier plate 52 pivoted at 54 on t e upper end of the driver bar arm, the plate having tack pockets 56'normally closed at their lower ends by a spring pressed gate 58 provided with a sloping bottom face 60 arranged to be engaged by the ends of the drivers 614: in their drivlng movement to cause the plate 58 to be pushed aside and permit the drivers to enter the tack pockets and expel the tacks therefrom. The plate 52 is provided with a tail portion 62 having surfaces 6 1 and 66 arranged to engage a stud 68 on the bracket 50 to determine the position of the plate, the tail 62 being held in enga ement with the stud by means of a spring 0 connected at one end to the tail and at its other end to a projection on c the driver bar arm. When the parts are in the positions indicated in Figs. 9 and 10 the surface 64: is in engagement with the stud 68 and the plate 52 is positioned in such relation to the drivers 614 and the tack block that the tacks are supported point upward in the pockets 56 and are in position to be driven upon the operative movement of the drivers. When the driver bar arm is moved to its inoperative position, which is toward the right in Figs. 9 and 10, the stud 68, in co-operation with the surface 66, permits the plate 52 to be swung by the spring 70 about the axis 54: to the dotted line position (Fig. 10), in which the pockets 56 are in line with the delivery ends of the conduits as. While the transfer plate is in this position tacks are forced through the conduits 4:8 and deposited, point upward, in the pockets 56 in the manner hereinbefore described. While the tack transferring means is illustrated in its relation to only one of the driver bar arms, it will be understood that each of the arms has similar mechanism associated therewith.

In order to control the admission of comressed air to the conduit 32, the valve 34 1s connected to a short shaft 72 upon which is secured a hub 74 provided with diametrically opposite ratchet teeth 76. Mounted loosely on the shaft 72 is an arm 78 provided with a spring pressed pawl 80, the arm 78 being rigid with a pinion 82 which is arranged to be turned in opposite directions alternately by the movement of a rack bar 84. The bar 84 is arranged to be moved toward the right (Fig. 1) during the pulling movement of the grippers in the first eriod of the cycle of operations of the machine through connection of the diametrically opposite tooth 76 without operating the valve. 34, a spring 90 on the bar 84 is compressed and a dog 92 ,on the bar 84 is caused to engage a sprin catch 94, whereby the rack bar is retaine in the osition to which it is moved. In the atter part of the finalperiod of the cycle of operations of the machine the return of the arm 86 effected by the return movement of the gripper operating means causes a tri 96 on the arm to engage the catch 91% an withdraw it from the dog 92 against the pressure of its spring in such manner as to permit the spring 90 to force the rack bar toward the left and effect an opening and a closing movement of the valve 34, movement of the rack bar in this direction bein In t is manner a blast of air is forced through the pipe 32 and the tacks are delivered pneumatically point upward to the carrier lates at a time when these plates are positioned to receive them while the driver bar arms are in their retracted position away from the shoe.

lln the use of the machine the operator stands close to the front frame late 2 in position to operate the treadle The work, positioned within easy reach or the operator, as indicated in dotted lines in Fig. 1, is below the level of the operators eyes and is inclined at such an angle as to afford the operator full view of the top of the upper and the portions round the sides of the forepart of the last without any special efiort upon his part such as would finally cause fatigue. The various handles which frequently require manipulation for the purpose of adjustin the upper, including the handles 158 an e, are so arranged as to be within easy reach of the operator as he stands in the position described without involving an obstruction of his view of the work. pon the first de ression of the treadle X the upper is pu led over the last in the well known manner through the action of the grippers, and at the same time the rack bar 84 is retracted in pre aration for the subsequent operation 0 the valve 34, the driver bar arms at this time being held in retracted position with the pockets 56 of the carrier plates 52 in line with the conduits 48 from which they have received inverted tacks in a previous operation of the machine. Upon a subsequent depression of the treadle, after any necessary adjustment of the upper on the ast has been eflected, the margin of the upper is carried inwardly under the retarded by means of a dash pot 98.

cause the several tacks supported on the separator plates 24 to be llfted and forced through the conduits 48 and deposited point u ward in the pockets56 whlch arrive in afinement with the conduits in time to receive the tacks.

Although the invention has been described with reference to a particular illustrative embodiment, it will be understood that various modifications in details are contemplated within the spirit and scopev of the claims.

It should be understood that the term inverted, except where the context requires a more limited interpretation, is used herein in a relative sense referring to substantial reversal of the position of a fastener end for end irrespective of any particular position which the fastener may occupy prior to such reversal.

Certain features of the construction herein shown, involving a combination of upper pulling means and fastenin means, are claimed in a divisional application, Serial No. 366,030, filed on March 15, 1920.
